FEATURES  
DESCRIPTION  
D
Two 340-m(Typical) High-Side MOSFETs  
200 mA Low-Dropout Voltage Regulator In  
Fixed 3.3-V or Adjustable Versions  
Two power-distribution switches and an adjustable  
(TPS2145) or fixed (TPS2147) LDO are incorporated in  
one small package, providing a power management  
solution that saves up to 60% in board space over  
typical implementations.

Overcurrent Indicators With Transient Filter  
2.9-V to 5.5-V Operating Range  
Designed to meet USB 2.0 bus-powered hub  
requirements, these devices also allow core and I/O  
voltage sequencing in DSP applications, or power  
segmentation in portable equipment. Each current-  
limited switch is a 340-mN-channel MOSFET capable  
of supplying 200 mA of continuous current. A logic  
enable compatible with 5-V logic and 3-V logic controls  
each MOSFET as well as the LDO in the TPS2145. The  
internal charge pump provides the gate drive controlling  
the power-switch rise times and fall times, minimizing  
current surges during switching. The charge pump  
requires no external components.  
CMOS- and TTL-Compatible Enable Inputs

APPLICATIONS  
D
USB Hubs and Peripherals  
− Keyboards  
− Zip Drives  
The LDO has a drop-out voltage of only 0.35 V and with  
the independent enable on the TPS2145 LDO, the LDO  
can be used as an additional switch. The LDO output  
range for the TPS2145 is 1 V to 3.3 V, while the  
TPS2147 is fixed at 3.3 V.

The TPS2145 and TPS2147 have active-low switch  
enables and the TPS2155 and TPS2157 have  
active-high switch enables.
